in the anode member or target of vacuum tu es used in the generation of. X and like .-rays, and has for-its object to provide a simple and eficient structural formation and combination of parts w ereby a very efliclent andpositive heat transference is attained.

during a continued use of the ray-tube, to permit of an extended use of powerful lngh tension currents ,which would otherwise damage or destroy the ray-tube after a very short period of actual use, all as will hereinafter more fully appear.

- ln the accompanying drawings: Figure 1, is a side elevation illustrating the general arrangement of parts of the present invention in an ordinary X-ray tube. Fig.2, is an enlarged detail longitudinal section illustrating the connection of the adjustable tube or conduit of the present invention and its accesories to the wall of the ray-tube. Fig. 3, is a detail end elevation of the same. Fig. t, is an enlarged detail longitudinal section of the anode or target and its accessories. Figs. 5 and 6, are side elevations illustrating modified arrangements of the parts.

Similar reference numerals indicate like parts in the several views.

The present application is a continuation in part of my prior application for Letters Fatent, Serial No. 788,597, filed Sept. 8,1913.

Referring to the drawings, 1 represents the main bulb of a ray-tube, provided with the usual auxiliary extensions in which are disposed the diflerent members or elements of the ray-tube.

2 is the cathode member, and 3 the anode member or target disposed in any usual opposed relation and having terminal connections extendingout through. the end walls of individual extensions of the main bulb in any usual and suitable manner.

a, is a tubular member of glass or the like, and which may be of an angular form, or a straight form, as shown in the drawings and as found most suitable by the constructor. Said tubular member is disposed in the l cn'roaao, rnnrno a specification of Letters Patent.

interior of the main bulb 1, and in the auxihary extensions 5 and 6 thereof, with the respective ends of the tubular member fused or similarly secured to the walls of said extensions 5, 6, as shown. The bore of the tubular member 4: contains the heat transference means hereinafter described, and in the present invention its respective ends are open to the atmosphere so that the tubular member will form a ventilating duct or flue for the passage of atmospheric air, to very eflectually aid in the removal of excess heat tgeiierated during the operation of the ray- 7 is a tube, preferably of metal, disposed longitudinally in one branch of the tubular member 4, aforesaid, with its inner and open end disposed in adjacent relation to the back or rear surface of the anode or target 3, and adapted to discharge a cooling medium against said target as hereinafter more fully set forth. In addition said tube 7 is directly connected to said anode or target 3 by a flexible or elastic conductor 8, so that in the hereinafter described adjustment of the tube 7 to and from the anode or target 3, electrical conductivity will be maintained between i the parts, to permit of the use of the tube 7 as a conducting means between the source of electrical supply and the anode or target 3.

9, is a fixed collar secured to the outer end of the auxiliary extension 5, of the main bulb 1, and provided with a central guide hub 10, connected to the collar 9 by'radial wings 11, as illustrated in Figs. 2 and 3. The bore of said hub 10, forms a support and guide for the metal tube 7, above described, to maintain the same in proper longitudinal alinement with the other parts of the ray-tube during its various adjustments to and from the anode 3, as above set forth.

12 is a collar or cap secured to the other auxiliary extension 6 of the ray-tube, and constructed in substantially the same manner as the collar 9 above described. Said collar or'cap will be provided with an outlet nipple 13, for the attachment of a hose to conduct away the fluid, when a fluid is employed as a cooling medium, as hereinafter more fully described.

Air or like gaseous fluid will be employed as the auxlliary cooling medium passing .through the tube '7 aforesaid, and supplied Patented ltllar, a. rats.

tinned actual use of the ray-tube.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is

1. In a ray-tube, the combination of a main body, a tubular memberpassing through said main body and open at its respective ends to the atmosphere to form a flue, means for effecting a draft through said tubular member, and an anode or target associated with said tubular member within the main body, substantially as set forth.

2. In a ray-tube, the combination of a main body, a tubular member of an angular form passing through said main body and open at its respective ends to the atmosphere to form a flue and an anode or target associated with said tubular member within the main body, substantially as set forth.

3. In a ray-tube, the combination of a main body, a tubular member passing through said main body and open at its respective ends to the atmosphere to form a flue, an anode or target associated with said tubular member within the main body, and a tube extending through said tubular memher into adjacent relation to the anode aforesaid and adapted to discharge a cooling medium against the same, substantially as set forth.

4. In a ray-tube, the combination of a main body, a tubular member passing through said main body and open at its respective ends to the atmosphere to form a flue, an anode or target associated with said tubular member within the main'body, and a tube extending through said tubular member into adj acent relation to the anode aforesaid and adapted to discharge a cooling medium against the same, the anode having heat dissipating projections adjacent'to the point of discharge from said tube, substantially as set forth.

5. In a ray-tube, the combination of a main body, a tubular member of an angular form passing through said main body and open at its respective ends to the atmosphere to form aflue, an anode or target associated with said tubular member within the main body, and a' tube extending through said tubular member into adjacent relation to the anode aforesaid. and adapted to discharge a cooling medium against the same, substantially as set forth.

6. In a ray-tube, the combination of a main body, a tubular member of an angular form passing through said main body and open at its respective ends to the atmosphere to form a flue, an anode or target associated with said tubular member within the main body, and a tube extending through said tubular member into adjacent relation to the anode aforesaid and adapted to discharge a cooling medium against the same, the anode having heat dissipating projections adjacent to the point of discharge from said tube, substantially as set forth.

7. In a ray-tube, the combination of a .main body, a tubular member passing through said main body and open at its respective ends to the atmosphere to form a flue, an anode or target associated with said tubular member within the main body, and a longitudinally adjustable tube extending through said tubular member into adjacent relation to the anode aforesaid and adapted to discharge a cooling medium against the same, substantially as set forth.

8. In a ray-tube, the combination of a main body, a tubular member passing through said main body and open at its respective ends to the atmosphere to form a flue, an anode or target associated with said tubular member within the main body and a longitudinally adjustable tube extending through said tubular member into adjacent relation to the anode aforesaid and adapted to discharge a cooling medium against the same, the anode having heat dissipating projections adjacent to the point of discharge from said tube, substantially as set forth.
